Research Description

The Fleming Group is studying dynamical processes in a range of complex systems, such as liquids, solutions and proteins. The major experimental tool is femtosecond spectroscopy which is combined with both theory and computer simulation to interpret the data.  

Their goal is to provide a molecular-level description of the role of solvents in chemical reactions and of the primary steps in natural photosynthesis.

They develop new types of spectroscopies, most recently two-dimensional electronic-vibrational (2DEV) spectroscopy which is being applied to energy transfer, proton-coupled electron transfer, proton transfer, and conical intersection dynamics.  We are also utilizing quantum light spectroscopy (entangled pairs of photons) to explore fundamental aspects of light matter interaction, and quantum coherence.

The primary events in photosynthesis involve energy transfer and electron transfer on ultrashort time scales. Use is made of genetic modification methods to investigate the role of the protein on these astonishingly efficient processes. Both bacterial, algal, and higher plant systems are studied with a particular current goal being to understand the mechanism of regulation of light harvesting in plants.  We also study synthetic systems with the goal of exploiting quantum coherence to create novel function.

Lessons to be Learned from Nature in Photosynthesis

Lessons to be learned from nature could lead to the development of an artificial version of photosynthesis that would provide us with an absolutely clean and virtually inexhaustible energy source, says Berkeley Lab photosynthesis authority Graham Fleming and three international colleagues.

Berkeley stakes science claim at Homestake gold mine

Berkeley stakes science claim at Homestake gold mine UC Berkeley and Berkeley Lab plan to turn South Dakota's Homestake gold mine into a world-class science complex, with underground experiments in astrophysics, physics, biology and earth science. South Dakota Gov. Mike Rounds, a big supporter of the effort, visited the campus and lab June 12 to cement the relationship and see what a large research complex looks like.
